Whenever I see an unexplained command I don't understand from a random internet forum, I hop onto the production server and run it, just in case it might boost performance. Wouldn't want to miss out on that.
Been doing it since I was 12. It taught me all about the ins and outs of `rm`.
Sounds like me back in the early 80s when I used to war dial, and people used to share "active" prefixes. I learned all about the 911 prefix when I set my dialer and went to sleep. About 20 minutes later the cops were banging on my front door. True story; I was in 6th grade, got arrested for it.
Reminds me of that story from an IRC channel:
A: I have a program that will format your hard drive. I just need your IP.
B: Ok, it's 127.0.0.1
A: Ahahaha, it 56% now! Lol.
